下载 .html 文件时输出不正确
Incorrect output when downloading .html files
我只想下载 python 中的 .html 个文件。
代码:
import urllib2
hdr = {'User-Agent': 'Mozilla/5.0'}
urls=['http://www.nydailynews.com/sports/soccer-fans-stampede-south-african-stadium-nigeria-north-korea-world-cup-warmup-article-1.179211']
path='C:/Users/sony/Desktop/Python'
for i,site in enumerate(urls):
print (site)
req = urllib2.Request(site, headers=hdr)
page = urllib2.build_opener(urllib2.HTTPCookieProcessor).open(req)
page_content = page.read()
with open(path+'/'+str(i)+'.html', 'w') as fid:
fid.write(page_content)
但这有时会给出这个输出
https://drive.google.com/file/d/0B16PrXUjs69zWFJvWmJ6aFhyN0k/view?usp=sharing
我根本不明白。
我在 python 中使用 goose 读取了这个文件,当我读取这样的文件时它什么也没显示。
通过查看回复 header:
>> print page.info()
Cache-Control: public, max-age=300, s-maxage=300
Content-Type: text/html;charset=utf-8
Server: fs3
Age: 103
Expires: Thu, 21 May 2015 13:36:40 GMT
Content-Encoding: gzip
Transfer-Encoding: chunked
Connection: close
Vary: Accept-encoding, Accept-Encoding
我看到内容是压缩的,尝试使用zlib模块解压缩数据。
要检查数据是否经过 gzip 压缩,请添加以下行:
if page.info().get('Content-Encoding', '') == 'gzip':
... # decompress data
请阅读 this 以获取如何解压缩 body 的示例。
使用 requests 为您完成所有工作,使用 .content
让请求处理编码:
import requests
urls=['http://www.nydailynews.com/sports/soccer-fans-stampede-south-african-stadium-nigeria-north-korea-world-cup-warmup-article-1.179211']
path='C:/Users/sony/Desktop/Python'
for i,site in enumerate(urls):
print (site)
req = requests.get(site)
page_content = req.content
with open ('{}{}.html'.format(path,i), 'w') as fid:
fid.write(page_content)
输出:
